       <STRONG>ncurses</STRONG> - CRT screen handling and optimization package


</PRE><H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>


</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       The  <STRONG>ncurses</STRONG>  library  routines  give the user a terminal-
       independent method of updating character screens with rea-
       sonable optimization.  This implementation is "new curses"
       (ncurses) and is the approved replacement for 4.4BSD clas-
       sic  curses,  which has been discontinued.  This describes
       <STRONG>ncurses</STRONG> version 6.0 (patch 20170401).

       The <STRONG>ncurses</STRONG> library emulates the curses library of  System
       V  Release  4  UNIX,  and  XPG4 (X/Open Portability Guide)
       curses (also known as XSI curses).  XSI stands for  X/Open
       System  Interfaces  Extension.   The  <STRONG>ncurses</STRONG>  library  is
       freely redistributable in source form.   Differences  from
       the  SVr4  curses  are summarized under the <STRONG>EXTENSIONS</STRONG> and
       <STRONG>PORTABILITY</STRONG> sections below and described in detail in  the
       respective  <STRONG>EXTENSIONS</STRONG>,  <STRONG>PORTABILITY</STRONG>  and <STRONG>BUGS</STRONG> sections of
       individual man pages.

       The <STRONG>ncurses</STRONG> library also provides many useful  extensions,
       i.e.,  features  which  cannot  be implemented by a simple
       add-on library but which require access to  the  internals
       of the library.

       A  program  using  these  routines must be linked with the
       <STRONG>-lncurses</STRONG> option, or (if it has been generated)  with  the
       debugging  library  <STRONG>-lncurses_g</STRONG>.   (Your system integrator
       may also have installed these libraries  under  the  names
       <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>.)  The ncurses_g library generates
       trace logs (in a file called 'trace' in the current direc-
       tory)  that describe curses actions.  See also the section
       on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.

       The <STRONG>ncurses</STRONG> package supports: overall screen,  window  and
       pad manipulation; output to windows and pads; reading ter-
       minal input; control over terminal and  <STRONG>curses</STRONG>  input  and
       output  options; environment query routines; color manipu-
       lation; use of soft label keys; terminfo capabilities; and
       access to low-level terminal-manipulation routines.


</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
       The  library uses the locale which the calling program has
       initialized.  That is normally done with <STRONG>setlocale</STRONG>:

               <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
     If the locale is not initialized, the library  assumes  that
     characters are printable as in ISO-8859-1, to work with cer-
     tain legacy programs.  You should initialize the locale  and
     not  rely on specific details of the library when the locale
     has not been setup.

       The function <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initial-
       ize the library before any of the other routines that deal
       with windows and screens are used.  The routine <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG>
       must be called before exiting.

       To  get  character-at-a-time  input  without echoing (most
       interactive, screen oriented programs want this), the fol-
       lowing sequence should be used:

               <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
     Most programs would additionally use the sequence:

             <STRONG>nonl();</STRONG>
             <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
             <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
   Before  a <STRONG>curses</STRONG> program is run, the tab stops of the terminal
   should be set and its initialization strings, if defined, must
   be  output.   This can be done by executing the <STRONG>tput</STRONG> <STRONG>init</STRONG> com-
   mand after  the  shell  environment  variable  <STRONG>TERM</STRONG>  has  been
   exported.   <STRONG>tset(1)</STRONG>  is  usually  responsible  for doing this.
   [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]


</PRE><H3><a name="h3-Datatypes">Datatypes</a></H3><PRE>
       The <STRONG>ncurses</STRONG> library permits manipulation  of  data  struc-
       tures,  called  <EM>windows</EM>,  which  can be thought of as two-
       dimensional arrays of characters representing all or  part
       of a CRT screen.  A default window called <STRONG>stdscr</STRONG>, which is
       the size of the terminal screen, is supplied.  Others  may
       be created with <STRONG>newwin</STRONG>.

       Note  that  <STRONG>curses</STRONG>  does  not  handle overlapping windows,
       that's done by the <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG> library.  This means that you
       can either use <STRONG>stdscr</STRONG> or divide the screen into tiled win-
       dows and not using <STRONG>stdscr</STRONG> at all.   Mixing  the  two  will
       result in unpredictable, and undesired, effects.

       Windows are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>.
       These  data  structures  are  manipulated  with   routines
       described  here and elsewhere in the <STRONG>ncurses</STRONG> manual pages.
       Among those, the most basic routines are <STRONG>move</STRONG>  and  <STRONG>addch</STRONG>.
       More  general versions of these routines are included with
       names beginning with <STRONG>w</STRONG>, allowing the  user  to  specify  a
       window.  The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.

       After  using  routines to manipulate a window, <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>
       is called, telling <STRONG>curses</STRONG> to make the  user's  CRT  screen
       look like <STRONG>stdscr</STRONG>.  The characters in a window are actually
       of type <STRONG>chtype</STRONG>, (character and  attribute  data)  so  that
       other  information  about the character may also be stored
       with each character.

       Special windows  called  <EM>pads</EM>  may  also  be  manipulated.
       These are windows which are not constrained to the size of
       the screen and whose contents need not be completely  dis-
       played.  See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG> for more information.

       In  addition  to  drawing  characters on the screen, video
       attributes and colors may be supported, causing the  char-
       acters  to show up in such modes as underlined, in reverse
       video, or in color on terminals that support such  display
       enhancements.  Line drawing characters may be specified to
       be output.  On input, <STRONG>curses</STRONG> is  also  able  to  translate
       arrow  and  function  keys  that transmit escape sequences
       into single values.  The video  attributes,  line  drawing
       characters,   and  input  values  use  names,  defined  in
       <STRONG>&lt;curses.h&gt;</STRONG>, such as <STRONG>A_REVERSE</STRONG>, <STRONG>ACS_HLINE</STRONG>, and <STRONG>KEY_LEFT</STRONG>.


</PRE><H3><a name="h3-Environment-variables">Environment variables</a></H3><PRE>
       If the environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> are set, or
       if  the program is executing in a window environment, line
       and column information in the  environment  will  override
       information read by <EM>terminfo</EM>.  This would affect a program
       running in an AT&amp;T 630 layer, for example, where the  size
       of a screen is changeable (see <STRONG>ENVIRONMENT</STRONG>).

       If  the environment variable <STRONG>TERMINFO</STRONG> is defined, any pro-
       gram using <STRONG>curses</STRONG> checks for a local  terminal  definition
       before  checking  in  the standard place.  For example, if
       <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the compiled terminal defini-
       tion is found in

               <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
     (The  <STRONG>a</STRONG>  is copied from the first letter of <STRONG>att4424</STRONG> to avoid
     creation of huge directories.)  However, if <STRONG>TERMINFO</STRONG> is  set
     to <STRONG>$HOME/myterms</STRONG>, <STRONG>curses</STRONG> first checks

             <STRONG>$HOME/myterms/a/att4424</STRONG>,
   and if that fails, it then checks

           <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
 This  is  useful for developing experimental definitions or when
 write permission in <STRONG>/usr/share/terminfo</STRONG> is not available.

       The integer  variables  <STRONG>LINES</STRONG>  and  <STRONG>COLS</STRONG>  are  defined  in
       <STRONG>&lt;curses.h&gt;</STRONG>  and will be filled in by <STRONG>initscr</STRONG> with the size
       of the screen.  The constants <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the val-
       ues <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.

       The  <STRONG>curses</STRONG>  routines  also  define  the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable
       <STRONG>curscr</STRONG> which is used for certain low-level operations like
       clearing  and  redrawing a screen containing garbage.  The
       <STRONG>curscr</STRONG> can be used in only a few routines.


</PRE><H3><a name="h3-Routine-and-Argument-Names">Routine and Argument Names</a></H3><PRE>
       Many <STRONG>curses</STRONG> routines have two or more versions.  The  rou-
       tines prefixed with <STRONG>w</STRONG> require a window argument.  The rou-
       tines prefixed with <STRONG>p</STRONG> require a pad argument.  Those with-
       out a prefix generally use <STRONG>stdscr</STRONG>.

       The routines prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate
       to move to before performing the appropriate action.   The
       <STRONG>mv</STRONG>  routines  imply  a call to <STRONG>move</STRONG> before the call to the
       other routine.  The coordinate <EM>y</EM> always refers to the  row
       (of  the  window), and <EM>x</EM> always refers to the column.  The
       upper left-hand corner is always (0,0), not (1,1).

       The routines prefixed with <STRONG>mvw</STRONG> take both a window argument
       and  <EM>x</EM>  and  <EM>y</EM> coordinates.  The window argument is always
       specified before the coordinates.

       In each case, <EM>win</EM> is the window affected, and <EM>pad</EM>  is  the
       pad affected; <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WIN-</STRONG>
       <STRONG>DOW</STRONG>.

       Option setting routines require a Boolean flag <EM>bf</EM> with the
       value  <STRONG>TRUE</STRONG>  or <STRONG>FALSE</STRONG>; <EM>bf</EM> is always of type <STRONG>bool</STRONG>.  Most of
       the data types used in the library routines, such as  <STRONG>WIN-</STRONG>
       <STRONG>DOW</STRONG>,  <STRONG>SCREEN</STRONG>,  <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are defined in <STRONG>&lt;curses.h&gt;</STRONG>.
       Types used for the terminfo routines such as <STRONG>TERMINAL</STRONG>  are
       defined in <STRONG>&lt;term.h&gt;</STRONG>.

       This  manual  page describes functions which may appear in
       any configuration of the library.  There  are  two  common
       configurations of the library:

          <EM>ncurses</EM>
               the  "normal" library, which handles 8-bit charac-
               ters.  The normal (8-bit) library  stores  charac-
               ters combined with attributes in <STRONG>chtype</STRONG> data.

               Attributes  alone (no corresponding character) may
               be stored in <STRONG>chtype</STRONG> or the equivalent <STRONG>attr_t</STRONG> data.
               In  either  case,  the data is stored in something
               like an integer.

               Each cell (row and column) in a <STRONG>WINDOW</STRONG>  is  stored
               as a <STRONG>chtype</STRONG>.

          <EM>ncursesw</EM>
               the so-called "wide" library, which handles multi-
               byte characters (see the section on <STRONG>ALTERNATE</STRONG> <STRONG>CON-</STRONG>
               <STRONG>FIGURATIONS</STRONG>).   The "wide" library includes all of
               the calls from  the  "normal"  library.   It  adds
               about  one third more calls using data types which
               store multibyte characters:

               <STRONG>cchar_t</STRONG>
                    corresponds  to  <STRONG>chtype</STRONG>.   However  it  is  a
                    structure,  because  more data is stored than
                    can fit into an integer.  The characters  are
                    large  enough to require a full integer value
                    - and there may be more  than  one  character
                    per cell.  The video attributes and color are
                    stored in separate fields of the structure.

                    Each cell (row and column)  in  a  <STRONG>WINDOW</STRONG>  is
                    stored as a <STRONG>cchar_t</STRONG>.

               <STRONG>wchar_t</STRONG>
                    stores a "wide" character.  Like <STRONG>chtype</STRONG>, this
                    may be an integer.

               <STRONG>wint_t</STRONG>
                    stores a <STRONG>wchar_t</STRONG> or  <STRONG>WEOF</STRONG>  -  not  the  same,
                    though both may have the same size.

               The  "wide"  library  provides new functions which
               are  analogous  to  functions  in   the   "normal"
               library.   There  is  a  naming  convention  which
               relates many of the normal/wide variants:  a  "_w"
               is  inserted  into  the name.  For example, <STRONG>waddch</STRONG>
               becomes <STRONG>wadd_wch</STRONG>.

</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       Routines  that  return  an integer return <STRONG>ERR</STRONG> upon failure
       and an integer value other than <STRONG>ERR</STRONG> upon  successful  com-
       pletion,  unless  otherwise  noted in the routine descrip-
       tions.

       As a general rule, routines check for null pointers passed
       as parameters, and handle this as an error.

       All  macros  return  the  value  of  the <STRONG>w</STRONG> version, except
       <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, and <STRONG>getmaxyx</STRONG>.  The

       and <STRONG>getmaxyx</STRONG> are undefined (i.e., these should not be used
       as the right-hand side of assignment statements).

       Routines that return pointers return <STRONG>NULL</STRONG> on error.


</PRE><H2><a name="h2-ENVIRONMENT">ENVIRONMENT</a></H2><PRE>
       The following environment symbols are useful for customiz-
       ing the runtime behavior of the <STRONG>ncurses</STRONG> library.  The most
       important ones have been already discussed in detail.

   <STRONG>CC</STRONG>
       When  set,  change  occurrences  of  the command_character
       (i.e.,  the  <STRONG>cmdch</STRONG>  capability)  of  the  loaded  terminfo
       entries  to the value of this variable.  Very few terminfo
       entries provide this feature.

       Because this name is also used in development environments
       to  represent the C compiler's name, <STRONG>ncurses</STRONG> ignores it if
       it does not happen to be a single character.


</PRE><H3><a name="h3-BAUDRATE">BAUDRATE</a></H3><PRE>
       The debugging library  checks  this  environment  variable
       when the application has redirected output to a file.  The
       variable's numeric value is used for the baudrate.  If  no
       value is found, <STRONG>ncurses</STRONG> uses 9600.  This allows testers to
       construct repeatable test-cases  that  take  into  account
       costs that depend on baudrate.


</PRE><H3><a name="h3-COLUMNS">COLUMNS</a></H3><PRE>
       Specify  the  width of the screen in characters.  Applica-
       tions running in a windowing environment usually are  able
       to  obtain  the width of the window in which they are exe-
       cuting.  If neither the <STRONG>COLUMNS</STRONG> value nor  the  terminal's
       screen  size is available, <STRONG>ncurses</STRONG> uses the size which may
       be specified in the  terminfo  database  (i.e.,  the  <STRONG>cols</STRONG>
       capability).

       It  is  important that your application use a correct size
       for the screen.  This is not always possible because  your
       application  may be running on a host which does not honor
       NAWS (Negotiations About Window Size), or because you  are
       temporarily  running  as  another  user.  However, setting
       <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG> overrides the library's  use  of  the
       screen size obtained from the operating system.

       Either  <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> symbols may be specified indepen-
       dently.  This is mainly useful to circumvent  legacy  mis-
       features  of terminal descriptions, e.g., xterm which com-
       monly specifies a 65 line screen.  For best results, <STRONG>lines</STRONG>
       and <STRONG>cols</STRONG> should not be specified in a terminal description
       for terminals which are run as emulations.

       Use the <STRONG>use_env</STRONG> function to disable all  use  of  external
       environment  (but not including system calls) to determine
       the screen size.  Use the <STRONG>use_tioctl</STRONG>  function  to  update
       <STRONG>COLUMNS</STRONG>  or  <STRONG>LINES</STRONG>  to match the screen size obtained from
       system calls or the terminal database.


</PRE><H3><a name="h3-ESCDELAY">ESCDELAY</a></H3><PRE>
       Specifies the  total  time,  in  milliseconds,  for  which
       ncurses  will await a character sequence, e.g., a function
       key.  The default value, 1000 milliseconds, is enough  for
       most  uses.  However, it is made a variable to accommodate
       unusual applications.

       The most common instance where you may wish to change this
       value  is to work with slow hosts, e.g., running on a net-
       work.  If the host cannot read characters rapidly  enough,
       it  will  have  the same effect as if the terminal did not
       send characters rapidly enough.  The  library  will  still
       see a timeout.

       Note  that  xterm mouse events are built up from character
       sequences received from the xterm.   If  your  application
       makes  heavy  use  of  multiple-clicking,  you may wish to
       lengthen this default value because the timeout applies to
       the  composed  multi-click event as well as the individual
       clicks.

       In addition to the environment variable, this  implementa-
       tion  provides a global variable with the same name.  Por-
       table applications should not rely upon  the  presence  of
       ESCDELAY in either form, but setting the environment vari-
       able rather than the global variable does not create prob-
       lems when compiling an application.


</PRE><H3><a name="h3-HOME">HOME</a></H3><PRE>
       Tells <STRONG>ncurses</STRONG> where your home directory is.  That is where
       it may read and write auxiliary terminal descriptions:

       $HOME/.termcap
       $HOME/.terminfo


</PRE><H3><a name="h3-LINES">LINES</a></H3><PRE>
       Like COLUMNS, specify the height of the screen in  charac-
       ters.  See COLUMNS for a detailed description.


</PRE><H3><a name="h3-MOUSE_BUTTONS_123">MOUSE_BUTTONS_123</a></H3><PRE>
       This  applies only to the OS/2 EMX port.  It specifies the
       order of buttons on the mouse.  OS/2  numbers  a  3-button
       mouse inconsistently from other platforms:

       1 = left
       2 = right
       3 = middle.

       This  variable lets you customize the mouse.  The variable
       must be three numeric digits 1-3 in any order,  e.g.,  123
       or 321.  If it is not specified, <STRONG>ncurses</STRONG> uses 132.


</PRE><H3><a name="h3-NCURSES_ASSUMED_COLORS">NCURSES_ASSUMED_COLORS</a></H3><PRE>
       Override  the  compiled-in  assumption that the terminal's
       default  colors  are  white-on-black   (see   <STRONG>default_col-</STRONG>
       <STRONG><A HREF="default_colors.3x.html">ors(3x)</A></STRONG>).  You may set the foreground and background color
       values with this environment variable by proving a  2-ele-
       ment  list:  foreground,background.   For example, to tell
       ncurses to not assume anything about the colors, set  this
       to  "-1,-1".   To make it green-on-black, set it to "2,0".
       Any positive value from zero to  the  terminfo  <STRONG>max_colors</STRONG>
       value is allowed.


</PRE><H3><a name="h3-NCURSES_CONSOLE2">NCURSES_CONSOLE2</a></H3><PRE>
       This applies only to the MinGW port of ncurses.

       The  <STRONG>Console2</STRONG>  program's handling of the Microsoft Console
       API call <STRONG>CreateConsoleScreenBuffer</STRONG> is defective.  Applica-
       tions  which  use this will hang.  However, it is possible
       to simulate the action of this  call  by  mapping  coordi-
       nates, explicitly saving and restoring the original screen
       contents.  Setting the environment variable <STRONG>NCGDB</STRONG> has  the
       same effect.


</PRE><H3><a name="h3-NCURSES_GPM_TERMS">NCURSES_GPM_TERMS</a></H3><PRE>
       This  applies  only  to  ncurses configured to use the GPM
       interface.

       If present, the environment variable is a list of  one  or
       more  terminal  names  against  which the <STRONG>TERM</STRONG> environment
       variable is matched.  Setting it to an  empty  value  dis-
       ables  the  GPM  interface; using the built-in support for
       xterm, etc.

       If  the  environment  variable  is  absent,  ncurses  will
       attempt to open GPM if <STRONG>TERM</STRONG> contains "linux".


</PRE><H3><a name="h3-NCURSES_NO_HARD_TABS">NCURSES_NO_HARD_TABS</a></H3><PRE>
       <STRONG>Ncurses</STRONG>  may use tabs as part of the cursor movement opti-
       mization.  In some cases, your  terminal  driver  may  not
       handle  these  properly.  Set this environment variable to
       disable the feature.  You can also adjust your  <STRONG>stty</STRONG>  set-
       tings  to avoid the problem.  NCURSES_NO_MAGIC_COOKIE Some
       terminals use a magic-cookie feature which  requires  spe-
       cial   handling  to  make  highlighting  and  other  video
       attributes display properly.  You can suppress  the  high-
       lighting  entirely  for  these  terminals  by setting this
       environment variable.


</PRE><H3><a name="h3-NCURSES_NO_PADDING">NCURSES_NO_PADDING</a></H3><PRE>
       Most of the terminal descriptions in the terminfo database
       are  written  for  real "hardware" terminals.  Many people
       use terminal emulators which run in a  windowing  environ-
       ment  and  use curses-based applications.  Terminal emula-
       tors can duplicate all of the important aspects of a hard-
       ware  terminal, but they do not have the same limitations.
       The chief limitation  of  a  hardware  terminal  from  the
       standpoint  of  your  application  is  the  management  of
       dataflow, i.e., timing.  Unless  a  hardware  terminal  is
       interfaced  into  a terminal concentrator (which does flow
       control), it (or your application) must  manage  dataflow,
       preventing  overruns.   The cheapest solution (no hardware
       cost) is for your program to  do  this  by  pausing  after
       operations that the terminal does slowly, such as clearing
       the display.

       As a result, many  terminal  descriptions  (including  the
       vt100)  have  delay  times  embedded.  You may wish to use
       these descriptions, but not want to  pay  the  performance
       penalty.

       Set the NCURSES_NO_PADDING environment variable to disable
       all but mandatory padding.  Mandatory padding is used as a
       part of special control sequences such as <EM>flash</EM>.


</PRE><H3><a name="h3-NCURSES_NO_SETBUF">NCURSES_NO_SETBUF</a></H3><PRE>
       This setting is obsolete.  Before changes

          <STRONG>o</STRONG>   started with 5.9 patch 20120825 and

          <STRONG>o</STRONG>   continued though 5.9 patch 20130126

       <STRONG>ncurses</STRONG>  enabled  buffered output during terminal initial-
       ization.  This was done (as in SVr4  curses)  for  perfor-
       mance  reasons.  For testing purposes, both of <STRONG>ncurses</STRONG> and
       certain applications,  this  feature  was  made  optional.
       Setting  the  NCURSES_NO_SETBUF  variable  disabled output
       buffering, leaving the output  in  the  original  (usually
       line buffered) mode.

       In  the  current  implementation, ncurses performs its own
       buffering and does not require this workaround.   It  does
       not modify the buffering of the standard output.

       The  reason  for  the  change was to make the behavior for
       interrupts and other signals more robust.  One drawback is
       that  certain  nonconventional programs would mix ordinary
       stdio calls with ncurses calls and (usually)  work.   This
       is  no  longer  possible  since  ncurses  is not using the
       buffered standard output but its own output (to  the  same
       file  descriptor).  As a special case, the low-level calls
       such as <STRONG>putp</STRONG> still use the  standard  output.   But  high-
       level curses calls do not.


</PRE><H3><a name="h3-NCURSES_NO_UTF8_ACS">NCURSES_NO_UTF8_ACS</a></H3><PRE>
       During initialization, the <STRONG>ncurses</STRONG> library checks for spe-
       cial cases where VT100 line-drawing (and the corresponding
       alternate  character  set  capabilities)  described in the
       terminfo are known to be missing.  Specifically, when run-
       ning in a UTF-8 locale, the Linux console emulator and the
       GNU screen program ignore these.  Ncurses checks the  <STRONG>TERM</STRONG>
       environment  variable for these.  For other special cases,
       you should set  this  environment  variable.   Doing  this
       tells  ncurses  to  use Unicode values which correspond to
       the VT100 line-drawing glyphs.  That works for the special
       cases cited, and is likely to work for terminal emulators.

       When setting this variable, you should set it to a nonzero
       value.  Setting it to zero (or to  a  nonnumber)  disables
       the special check for "linux" and "screen".

       As  an  alternative  to  the environment variable, ncurses
       checks for an extended terminfo capability <STRONG>U8</STRONG>.  This is  a
       numeric  capability  which  can  be compiled using <STRONG>tic</STRONG> <STRONG>-x</STRONG>.
       For example

          # linux console, if patched to provide working
          # VT100 shift-in/shift-out, with corresponding font.
          linux-vt100|linux console with VT100 line-graphics,
                  U8#0, use=linux,

          # uxterm with vt100Graphics resource set to false
          xterm-utf8|xterm relying on UTF-8 line-graphics,
                  U8#1, use=xterm,

       The name "U8" is chosen to be two characters, to permit it
       to  be  used  by  applications  that  use ncurses' termcap
       interface.


</PRE><H3><a name="h3-NCURSES_TRACE">NCURSES_TRACE</a></H3><PRE>
       During  initialization,  the  <STRONG>ncurses</STRONG>  debugging   library
       checks  the  NCURSES_TRACE environment variable.  If it is
       defined, to a numeric value, <STRONG>ncurses</STRONG> calls the <STRONG>trace</STRONG> func-
       tion, using that value as the argument.

       The  argument  values, which are defined in <STRONG>curses.h</STRONG>, pro-
       vide several types  of  information.   When  running  with
       traces enabled, your application will write the file <STRONG>trace</STRONG>

       <STRONG>TERM</STRONG>  is commonly set by terminal emulators to help appli-
       cations find a workable  terminal  description.   Some  of
       those   choose  a  popular  approximation,  e.g.,  "ansi",
       "vt100", "xterm" rather than an  exact  fit.   Not  infre-
       quently,  your  application  will  have problems with that
       approach, e.g., incorrect function-key definitions.

       If you set <STRONG>TERM</STRONG> in your environment, it has no  effect  on
       the  operation  of the terminal emulator.  It only affects
       the way applications work within the terminal.   Likewise,
       as a general rule (<STRONG>xterm</STRONG> being a rare exception), terminal
       emulators which allow you to specify <STRONG>TERM</STRONG> as  a  parameter
       or  configuration  value  do  not change their behavior to
       match that setting.

       If the <STRONG>ncurses</STRONG> library has been  configured  with  <EM>termcap</EM>
       support,  <STRONG>ncurses</STRONG>  will check for a terminal's description
       in termcap form if it is not  available  in  the  terminfo
       database.

       The  <STRONG>TERMCAP</STRONG> environment variable contains either a termi-
       nal description (with newlines stripped out),  or  a  file
       name  telling  where  the  information denoted by the <STRONG>TERM</STRONG>
       environment variable exists.  In either case,  setting  it
       directs  <STRONG>ncurses</STRONG> to ignore the usual place for this infor-
       mation, e.g., /etc/termcap.


</PRE><H3><a name="h3-TERMINFO">TERMINFO</a></H3><PRE>
       <STRONG>ncurses</STRONG> can be configured to read from  multiple  terminal
       databases.   The  <STRONG>TERMINFO</STRONG> variable overrides the location
       for the default terminal database.  Terminal  descriptions
       (in terminal format) are stored in terminal databases:

       <STRONG>o</STRONG>   Normally  these  are stored in a directory tree, using
           subdirectories named by the first letter of the termi-
           nal names therein.

           This is the scheme used in System V, which legacy Unix
           systems use, and the  <STRONG>TERMINFO</STRONG>  variable  is  used  by
           <EM>curses</EM>  applications  on those systems to override the
           default location of the terminal database.

       <STRONG>o</STRONG>   If <STRONG>ncurses</STRONG> is built to use hashed databases, then each
           entry  in  this list may be the path of a hashed data-
           base file, e.g.,

             /usr/share/terminfo.db

           rather than

             /usr/share/terminfo/

           The hashed database uses less disk-space and is a lit-
           tle  faster  than  the  directory tree.  However, some
           applications assume the  existence  of  the  directory
           tree,  reading  it directly rather than using the ter-
           minfo library calls.

       <STRONG>o</STRONG>   If <STRONG>ncurses</STRONG> is built with a support for reading termcap
           files  directly, then an entry in this list may be the
           path of a termcap file.

       <STRONG>o</STRONG>   If the <STRONG>TERMINFO</STRONG> variable begins with "hex:" or "b64:",
           <STRONG>ncurses</STRONG>  uses the remainder of that variable as a com-
           piled terminal description.   You  might  produce  the
           base64 format using <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG>:

             TERMINFO="$(infocmp -0 -Q2 -q)"
             export TERMINFO

           The  compiled description is used if it corresponds to
           the terminal identified by the <STRONG>TERM</STRONG> variable.

       Setting <STRONG>TERMINFO</STRONG> is the simplest, but not the only way  to
       set  location  of the default terminal database.  The com-
       plete list of database locations in order follows:

          <STRONG>o</STRONG>   the last terminal database to which <STRONG>ncurses</STRONG>  wrote,
              if any, is searched first

          <STRONG>o</STRONG>   the  location specified by the TERMINFO environment
              variable

          <STRONG>o</STRONG>   $HOME/.terminfo

          <STRONG>o</STRONG>   locations listed in the  TERMINFO_DIRS  environment
              variable

          <STRONG>o</STRONG>   one  or  more  locations whose names are configured
              and compiled into the ncurses library, i.e.,

             <STRONG>o</STRONG>   /usr/local/ncurses/share/ter-
                 minfo:/usr/share/terminfo  (corresponding to the
                 TERMINFO_DIRS variable)

             <STRONG>o</STRONG>   /usr/share/terminfo (corresponding to  the  TER-
                 MINFO variable)


</PRE><H3><a name="h3-TERMINFO_DIRS">TERMINFO_DIRS</a></H3><PRE>
       Specifies  a  list  of  locations  to  search for terminal
       descriptions.  Each location in the  list  is  a  terminal
       database as described in the section on the <STRONG>TERMINFO</STRONG> vari-
       able.  The list is separated  by  colons  (i.e.,  ":")  on
       Unix, semicolons on OS/2 EMX.

       There is no corresponding feature in System V terminfo; it
       is an extension developed for <STRONG>ncurses</STRONG>.


</PRE><H3><a name="h3-TERMPATH">TERMPATH</a></H3><PRE>
       If <STRONG>TERMCAP</STRONG> does not hold a file name then  <STRONG>ncurses</STRONG>  checks
       the  <STRONG>TERMPATH</STRONG>  environment  variable.   This  is a list of
       filenames separated by spaces or  colons  (i.e.,  ":")  on
       Unix, semicolons on OS/2 EMX.

       If  the  <STRONG>TERMPATH</STRONG> environment variable is not set, <STRONG>ncurses</STRONG>
       looks in the files

         /etc/termcap, /usr/share/misc/termcap and $HOME/.termcap,

       in that order.

       The library may be configured to disregard  the  following
       variables  when  the current user is the superuser (root),
       or if the application uses setuid or setgid permissions:

         $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.


</PRE><H2><a name="h2-ALTERNATE-CONFIGURATIONS">ALTERNATE CONFIGURATIONS</a></H2><PRE>
       Several different configurations are  possible,  depending
       on   the  configure  script  options  used  when  building
       <STRONG>ncurses</STRONG>.  There are a few main options whose  effects  are
       visible to the applications developer using <STRONG>ncurses</STRONG>:

       --disable-overwrite
            The  standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYN-</STRONG>
            <STRONG>OPSIS</STRONG>:

          <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>

            This option is used to avoid filename conflicts  when
            <STRONG>ncurses</STRONG>  is  not the main implementation of curses of
            the computer.   If  <STRONG>ncurses</STRONG>  is  installed  disabling
            overwrite,  it  puts  its  headers in a subdirectory,
            e.g.,

          <STRONG>#include</STRONG> <STRONG>&lt;ncurses/curses.h&gt;</STRONG>

            It also omits a symbolic link which would  allow  you
            to use <STRONG>-lcurses</STRONG> to build executables.

       --enable-widec
            The  configure script renames the library and (if the
            <STRONG>--disable-overwrite</STRONG> option is used) puts  the  header
            files  in  a  different  subdirectory.   All  of  the
            library names have a  "w"  appended  to  them,  i.e.,
            instead of

          <STRONG>-lncurses</STRONG>

            you link with

          <STRONG>-lncursesw</STRONG>

            You must also define <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> when com-
            piling for the  wide-character  library  to  use  the
            extended  (wide-character)  functions.   The <STRONG>curses.h</STRONG>
            file  which  is  installed  for  the   wide-character
            library  is designed to be compatible with the normal
            library's header.  Only the size of the <STRONG>WINDOW</STRONG> struc-
            ture  differs, and very few applications require more
            than a  pointer  to  <STRONG>WINDOW</STRONG>s.   If  the  headers  are
            installed   allowing  overwrite,  the  wide-character
            library's headers should be installed last, to  allow
            applications  to  be  built using either library from
            the same set of headers.

       --with-pthread
            The configure script renames the library.  All of the
            library names have a "t" appended to them (before any
            "w" added by <STRONG>--enable-widec</STRONG>).

            The global variables such as <STRONG>LINES</STRONG>  are  replaced  by
            macros  to allow read-only access.  At the same time,
            setter-functions are provided to  set  these  values.
            Some  applications  (very few) may require changes to
            work with this convention.

       --with-shared

       --with-normal

       --with-debug

       --with-profile
            The shared and normal (static) library  names  differ
            by  their  suffixes,  e.g.,  <STRONG>libncurses.so</STRONG>  and <STRONG>libn-</STRONG>
            <STRONG>curses.a</STRONG>.  The debug and profiling  libraries  add  a
            "_g" and a "_p" to the root names respectively, e.g.,
            <STRONG>libncurses_g.a</STRONG> and <STRONG>libncurses_p.a</STRONG>.

       --with-trace
            The <STRONG>trace</STRONG> function  normally  resides  in  the  debug
            library, but it is sometimes useful to configure this
            in the  shared  library.   Configure  scripts  should
            check for the function's existence rather than assum-
            ing it is always in the debug library.

       The  <STRONG>ncurses</STRONG>  library  can  be  compiled  with  an  option
       (<STRONG>-DUSE_GETCAP</STRONG>) that falls back to the old-style /etc/term-
       cap file if the terminal setup code cannot find a terminfo
       entry corresponding to <STRONG>TERM</STRONG>.  Use of this feature  is  not
       recommended,  as it essentially includes an entire termcap
       compiler in the <STRONG>ncurses</STRONG> startup code, at significant  cost
       in core and startup cycles.

       The  <STRONG>ncurses</STRONG>  library  includes  facilities  for capturing
       mouse events on certain terminals (including xterm).   See
       the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.

       The  <STRONG>ncurses</STRONG> library includes facilities for responding to
       window resizing events, e.g., when running  in  an  xterm.
       See  the  <STRONG><A HREF="resizeterm.3x.html">resizeterm(3x)</A></STRONG>  and <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual pages for
       details.  In addition, the library may be configured  with
       a SIGWINCH handler.

       The  <STRONG>ncurses</STRONG> library extends the fixed set of function key
       capabilities of  terminals  by  allowing  the  application
       designer  to  define  additional key sequences at runtime.
       See the <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG> <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>, and <STRONG><A HREF="keyok.3x.html">keyok(3x)</A></STRONG> man-
       ual pages for details.

       The <STRONG>ncurses</STRONG> library can exploit the capabilities of termi-
       nals which implement the ISO-6429 SGR 39 and SGR  49  con-
       trols, which allow an application to reset the terminal to
       its original foreground and background colors.   From  the
       users'  perspective,  the application is able to draw col-
       ored text on a background  whose  color  is  set  indepen-
       dently,  providing  better  control  over color contrasts.
       See the <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG> manual page for details.

       The <STRONG>ncurses</STRONG> library  includes  a  function  for  directing
       application  output  to a printer attached to the terminal
       device.  See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual page for details.


</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       The <STRONG>ncurses</STRONG> library is intended to be  BASE-level  confor-
       mant with XSI Curses.  The EXTENDED XSI Curses functional-
       ity (including color support) is supported.

       A small number of local differences (that  is,  individual
       differences  between the XSI Curses and <STRONG>ncurses</STRONG> calls) are
       described in  <STRONG>PORTABILITY</STRONG>  sections  of  the  library  man
       pages.

       Unlike  other  implementations, this one checks parameters
       such as pointers to WINDOW structures to ensure  they  are
       not  null.  The main reason for providing this behavior is
       to guard against programmer error.  The standard interface
       does not provide a way for the library to tell an applica-
       tion which  of  several  possible  errors  were  detected.
       Relying  on  this (or some other) extension will adversely
       affect the portability of curses applications.

       This implementation also contains several extensions:

       <STRONG>o</STRONG>   The routine <STRONG>has_key</STRONG> is not part of  XPG4,  nor  is  it
           present  in  SVr4.  See the <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> manual page
           for details.

       <STRONG>o</STRONG>   The routine <STRONG>slk_attr</STRONG> is not part of XPG4,  nor  is  it
           present in SVr4.  See the <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG> manual page for
           details.

       <STRONG>o</STRONG>   The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>, <STRONG>ungetmouse</STRONG>, <STRONG>mousein-</STRONG>
           <STRONG>terval</STRONG>, and <STRONG>wenclose</STRONG> relating to mouse interfacing are
           not part of XPG4, nor are they present in  SVr4.   See
           the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.

       <STRONG>o</STRONG>   The  routine  <STRONG>mcprint</STRONG>  was not present in any previous
           curses implementation.  See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG>  manual
           page for details.

       <STRONG>o</STRONG>   The  routine  <STRONG>wresize</STRONG>  is  not part of XPG4, nor is it
           present in SVr4.  See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page  for
           details.

       <STRONG>o</STRONG>   The  WINDOW structure's internal details can be hidden
           from application programs.   See  <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG>  for
           the discussion of <STRONG>is_scrollok</STRONG>, etc.

       <STRONG>o</STRONG>   This implementation can be configured to provide rudi-
           mentary support for multi-threaded applications.   See
           <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG> for details.

       <STRONG>o</STRONG>   This  implementation can also be configured to provide
           a set of functions which improve the ability to manage
           multiple screens.  See <STRONG><A HREF="curs_sp_funcs.3x.html">curs_sp_funcs(3x)</A></STRONG> for details.

       In  historic curses versions, delays embedded in the capa-
       bilities <STRONG>cr</STRONG>, <STRONG>ind</STRONG>, <STRONG>cub1</STRONG>, <STRONG>ff</STRONG> and <STRONG>tab</STRONG> activated corresponding
       delay  bits  in  the UNIX tty driver.  In this implementa-
       tion, all padding is done  by  sending  NUL  bytes.   This
       method  is slightly more expensive, but narrows the inter-
       face to the UNIX kernel significantly  and  increases  the
       package's portability correspondingly.

       If standard output from a <STRONG>ncurses</STRONG> program  is  re-directed

       directed to standard error.  This was an undocumented fea-
       ture of AT&amp;T System V Release 3 curses.
